The state of infrastructure in many developed countries around the world is an increasingly pressing issue, with mounting costs longer repairs are deferred. In today’s rapidly urbanising world, urban rail network particularly critical, since failures can have severe economic consequences for both operator’s finances and user time costs. This paper thus provides a system-level model welfare-orie...

Enhancement of the photoluminescence (PL) of colloidal CdSe and (core)shell (CdSe)ZnS quantum dots has been observed when the dots are illuminated above the band-gap energy. The effect occurs in dots suspended in a variety of organic or aqueous environments. During periods of constant illumination, the exciton PL quantum yield was found to reach a value of up to 60 times that of the solution of...

On January 25, 2013, the Department of Health and Human Services (“HHS”) published final regulations making important changes to requirements under the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”). The final regulations are the result of a rulemaking process that has taken over two years and implement changes made in the Health Information Technology for Economic and Cl...

The American Recovery and Reinvestment Act identified secure patient-physician e-mail messaging as an objective of the meaningful use of electronic health records. In our study of 35,423 people with diabetes, hypertension, or both, the use of secure patient-physician e-mail within a two-month period was associated with a statistically significant improvement in effectiveness of care as measured...

The Dasgupta-Heal-Solow-Stiglitz model of capital accumulation and resource depletion poses the following sustainability problem: is it feasible to sustain indefinitely a level of consumption that is bounded away from zero? We provide a complete technological characterization of the sustainability problem in this model without reference to the time path. As a byproduct we show general existence...

The American Recovery and Reinvestment Act (ARRA) of 2009 will soon provide billions of dollars to small physician practices nationwide to encourage adoption of electronic health records. Although shifting from paper to computers should lead to better and cheaper care, the transition is complex. In this paper we describe our struggles to adapt a commercial electronic health record to an innovat...

Enterprise electronic medical records (EMR) have largely become a standard since their use was mandated by The American Recovery and Reinvestment Act of 2009. However, perfusion departments have adopted true perfusion EMRs at various rates. In our efforts to integrate with the institutions EMR while enjoying the benefits of an EMR designed specifically for perfusion practice, we developed a dis...

We develop a tractable model of realization utility that studies the role of referencedependent S-shaped preferences in a dynamic investment setting with reinvestment. Our model generates both voluntarily realized gains and losses. It makes specific predictions about the volume of gains and losses, the holding periods, and the sizes of both realized and paper gains and losses that can be calibr...
